LUBRICATING MEANS FOR TWISTER RINGS.

Application filed April 8,

To all whom it may concern:

Be it known that I, DONIGAN D. Townes, a citizen of the United States, residing in Baltimore city, State of Maryland, have in-v vented certain new and useful Improvementsin Lubricating Means for Twister Rings, of which the following is a specification.

My said invention relates to a lubricating device for twister rings and it is an object of the same to provide a simple and effective attachment which shall be adapted to furnish oil to the contacting surfaces of the ring and traveler for considerable periods of time without requiring attention on the part of an operative. In ordinary mill practice it is customary to supply lubricant to the inner face of the twister ring with the finger and this must be done at relatively frequent intervals whereas the building of a spool requires a relatively long time. In t is way also there is a periodic variation from an excess of lubricant to a deficiency thereof, which makes for uneven twisting whereas with my device this factor of variation is eliminated, the lubrication being always uniform, and this results in a more evenly twisted yarn.

Referring to the accompanying drawing which is made a part hereof, and on which similar reference characters indicate similar parts, I

The figure is a perspective of a twister ring and its traveler with my device in place on the ring and with parts broken away to show the interior of-the lubricator.

In the drawings reference character 10 in dicates a twister ring, and 11 a traveler, both of these devices being of an ordinary type well known in the art. The ring has an annular enlargement at 12 and a narrower annular enlargement 13 at the upper edge of the first. The oil cup 14 has a neck portion 15 secured to the part 12 preferably by a tubular extension 16 passing through the ring and firmly secured thereto by soldering or in any other convenient manner. The conduit from the interior of the cup to the interior of the ring slopes upward and is provided with a packing of'fibrous material 17 the feed of oil being by capillary attraction only and not by gravity, as otherwise an excess of oil would run out over the inner face of the ring, particularly when the traveler is stationary, as for dofiing. The cup has a pivoted cap 18 of ordinary 1922. Serial No. 550,749.

type which is held in closed position by a. spring 19 surrounding the pivot 20.

In the operation of the device the traveler moves round and round on the ring with its adjacent surfaces in more or less contact with the inner surface of the ring. As it passes the oil cup it picks up a minute quantity of oil from the packing 17 and distributes the same about the inner surface of the ring. The feed of oil can readily be regulated by varying the nature of the packing and by forcing it more or less tightly into the conduit. In this way I provide for uniform and constant oiling of the inner surface of the ring whereas in the ordinary practice an excess quantity of oil is applied by the finger resulting in the soiling of a considerable length of yarn and this must be repeated at relatively frequent intervals to prevent the parts running dry with conse uent damage to them and to the yarn.

' aving thus fully described my said invention what I claim as new and desire to secure by Letters Patent, is:

1. In a twister ring an oil cup supported on the exterior of the ring and having an opening at the bottom for communication with the inner face thereof said connection comprising an upwardly inclined passage, and means within the passage for feeding liquid oil up the passage from-the oil cup to the inner face of the ring, substantially as set forth.

2. In a twister ring, means for lubricating the inner face of the ring comprising an oil cup supported on the ring and having an opening at the bottom thereof said ring having an upwardly inclined conduit opening upon the inner face of the same and a packing in said conduit to effect and to regulate the flow of oil, substantially as set forth.

3. In a twister ring, means for lubricating the inner face .of the ring comprising an oil cup supported on the ring and having an upwardly sloping conduit opening upon the inner face of the same and a packing in said conduit to feed the oil by capillary attraction only, substantially as set forth.

4. A twister ring provided with a lubricant reservoir on its outside and a capillary feeder leading upwardly from said reservoir to the inner surface of the ring, substantially as set forth.

5. A twister ring having a lubricant reservoir and a channel leading upwardly my hand and seal atWashington, Districtfrom said lubricant reservoir to the inner of Columbia, this 6th day of April, A. D. surface of the twister ring, and means withnineteen hundred and twenty-two.
